There are two main types of cemented carbide round rods: one is tungsten carbide and cobalt made of cemented carbide rod, and the other is cermet round rods made of cermet.

Tungsten carbide rod that with good hardness, coupled with excellent strength, widely accepted. Although cermet rod is not as widely used as tungsten carbide rod, but it with super hardness and could reach 93HRA. And suitable for some super-hard working conditions or high temperature environment, it has a very good performance.

Here we mainly introduce the carbide round rods with coolant holes, which are more difficult to produce than the whole round rods, so they are relatively expensive. At the same time it can be divided into straight hole round rod and spiral hole round rod, straight hole

Carbide round rods with cooling holes are mainly processed into drill bits, which are used for high speed drilling to reduce the temperature, avoid burning the bit, and increase the service life of the tool.

Tungsten Carbide rod is mainly used for drill, end milling cutter and reamer. It can also be used for cutting, stamping and measuring tools. It is used in papermaking, packaging, printing, nonferrous metal processing

Industry, in addition, it is widely used in the processing of high speed steel tools, carbide milling cutter, carbide cutting tools, cutting tools, aviation tools, carbide drill, milling core

The drill bit.High speed steel, metric milling cutter, Micro end milling cutter, reaming pilot, electronic cutter, step drill, metal cutting saw, double margin drill, gun rod, Angle milling cutter, hard

Alloy rotary file, carbide tool, etc.

Q: Can you order only 1KG to try the material?

Answer: Of course! By the way, I would like to say one more thing, what material we send for you to test that will be used for your re-order in the later period. There will be no poor material mixed in the cargos to sell to you after getting the trust of customers like some peers.
